In addition, the present invention refers to the method for liquid reflux suction-filter-pump in treating the types of waste liquid into potable water by using this apparatus.

A filtration device comprising a media basket, a baseplate, and a canister. The media basket is affixed to the baseplate. The canister has a cavity therein and is detachably coupled with the baseplate to enclose the media basket. The media basket contains a porous filtration material that efficiently removes contaminants from liquid. The device is configured to establish a first siphon to convey liquid from outside the device into the canister cavity through a canister pipe when a liquid level outside the filtration device is higher than the top of the weir in the canister pipe and configured to establish a second siphon to convey liquid from canister cavity through the top of a center riser pipe and out an outlet pipe when the first siphon has been established and the liquid level outside the filtration device is higher than the top of the center riser pipe.

An oil conditioner is provided for removing impurities from oil, such as water, fuel and glycol, to increase engine life and efficiency. An evaporator assembly includes an upper plate, a lower plate, with a heater unit sandwiched between the two. To increase the efficiency of the evaporator assembly, materials are selected so that the upper plate thermal conductivity property is greater than the lower plate thermal conductivity property; and, optionally, the lower plate includes a reflective surface to direct thermal radiation toward the upper plate. This unique design enables oil conditioning with reduced power consumption and improved heating compared to existing technology.
